Grundig WKC 5600 RDS

[LMAG]

Hi,
I'm recovering an old Suzuki Samurai and will try to certify it as a collectors car. Need to instal my old Grundig WKC 5600 as a "correct" car radio from that time. unfortunately, just lost de unlock code.
Need the code for SN GR0983T0109133
Kindly ask your help to go over one more obstacle.
Cheers
